Hi,
Using Cisco umbrella roaming agent in Windows 10 computers. Agent stays in unprotected state always, but there's internet connectivity and even tracert to opendns IP works.
anyone any idea why?
Log shows like;

It's probably because the client device doesn't have full connectivity to the Umbrella cloud. What protocols/ports are you permitting to the Umbrella cloud servers?
Unprotected—The policy is not currently being enforced; the computer is unable to communicate with our DNS servers.
Refer to the following guides for the protocols/ports/IP addresses:-

Thank you @Rob Ingram
it's just windows system and internet. There's only internet router in between.
UDP 53 and TCP 443 are open for sure.
Tracert to opendns IP are working.

Check you .NET framework, it needs to be 4.5 or greater.

Hi @Rob Ingram
Wondering whether Umbrella sends any alert if an agent goes into unprotected state. How else can an administrator know one of their employee laptop is not protected and their system is compromised.
